This project has its origin in a lecture by a member of NASA.  The lecturer was encouraging beekeepers to acquire a farm platform scale to weigh beehives and then report the weights.  The weight infomation was to be used as part of a climate change study.  The theory was that if climate warming caused earlier blooming of plants, the weight of beehives would increase earlier when the bees foraged for nectar.

Farm platform scales are difficult to find and expensive.  They also have the drawback of not being readily movable.  This limits the feasible data collection to one hive.

The BeeWeigh  project was started to develop a light-weight, inexpensive and easy-to-move device that could be used to weigh multiple hives in a short period of time.  After numerous changes, the current device meets the initial objectives.  It employs the simple scientific principles of leverage to reduce the amount of effort required to weigh a heavy hive.

The BeeWeigh requires some skill at woodworking.  Other materials and cruder materials could be used to implement the same principles.  

It also requires a small amount of mathematics to arrive at the end results.  A small, programmable calculator is very handy in this area. However, the mathematics can be greatly simplified by creating and printing a spreadsheet look-up table that computes the results of weighing a hive in convenient increments of about 2 ounces over the typical range of hive gross weights.
